With the Fluke 773, you can measure current loops without interrupting them. The significant advantage is that the connected components do not need to be taken offline or bypassed for maintenance and verification of the loop. This saves time when testing analog inputs and outputs on a PLC. Additionally, this type of measurement can prevent the accidental opening of a critical loop, which could cause operational voltage failures. Furthermore, you can measure current loops directly on the device using serial measurement sockets, provide and simulate signals between 4 and 20 mA, and measure current loops while simultaneously powering the loop with 24 V. You can supply mA output signals with a linear ramp or a 25% step output signal, with the 4 to 20 mA output signal automatically adjusted for tests over longer distances. Additionally, you can measure DC voltages up to 30 V and provide DC voltage of 1 - 5 V or 0 - 10 V. Scaled mA outputs offer a continuous mA signal that corresponds to the 4 to 20 mA signal measured by the mA current clamp. The mA output signal allows a digital logging multimeter or another device to record 4 to 20 mA signals without interrupting the loop. Moreover, you have an mA input/output available: simultaneous measurement of the mA signal with the current clamp and provision of an mA signal. You can input an mA signal into the input of an instrument and measure 4 to 20 mA at the output of the instrument, such as at valves or mA isolators.
